  1. Coat parts indicated by arrows with molybdenum disulfide lithium base grease . See «COMPONENTS»(ref-172948-S11214112772005030700000) .
  2. Install main shaft assembly : Using a snap ring expander, install a new snap ring on the lower side. Install the main shaft assembly. Using a snap ring expander, install a new snap ring on the upper side.
  3. Install main shaft bushing : Coat a new bushing with molybdenum disulfide lithium base grease. Using SST and a hammer, tap in the main shaft bushing. SST 09612-22011
  4. Install break away bracket and tilt lever : Install the clamp and No. 2 support collar to the break away bracket. NOTE: Align the holes in the column tube with the projections of the tilt lever lock bolt and stopper. Install the break away bracket, tilt lever lock bolt, stopper and tilt lever. Install the adjusting nut by rotating it counterclockwise in the specified torque so that the locking load (load applied to when a knob is operated) of the tilt lever will be 43 - 91 N (4.4 - 9.3 kgf, 9.7 - 20.5lbf). Torque: 9 N.m - 14 N.m (90 kgf.cm - 145 kgf.cm, 80 in.lbf - 10 ft.lbf) NOTE: Align the No. 1 support reinforce with the nut to eliminate looseness by turning the No. 1 support reinforce counterclockwise a little, then torque the No. 2 tilt lever lock bolt. Install the No. 1 support reinforce with the No. 2 tilt lever lock bolt by turning it counterclockwise. Torque: 5.4 N.m (55 kgf.cm, 48 in..lbf)
  5. Install 2 No. 1 support collars and bracket spacer : Install 2 new No. 1 support collars. Using an extension bar and a hammer, drive in the bracket spacer.
  6. Install column upper bracket and column upper clamp

  1. Install No. 2 intermediate shaft assembly : Align the match-marks on the No. 2 intermediate shaft assembly and main shaft assembly. Install the No. 2 intermediate shaft assembly with the bolt. Torque: 28 N.m (290 kgf.cm, 21 ft.lbf)
  2. Install sliding yoke : Temporarily install the sliding yoke to the No. 2 intermediate shaft assembly with the bolt A.
  3. Install steering column : Install the steering column assembly with the lower mount bolt and 2 upper mount bolts. Torque: 21 N.m (210 kgf.cm, 15 ft.lbf) Connect the connectors.
  4. Connect sliding yoke : Align the match-marks on the sliding yoke and No. 3 intermediate shaft assembly. Install the bolt B. Torque: 28 N.m (290 kgf.cm, 21 ft.lbf) Torque the bolt A. Torque: 28 N.m (290 kgf.cm, 21 ft.lbf)
  5. Install No. 2 column hole cover : Install the No. 2 column hole cover with the clip.
  6. A/T, install key interlock cable . See «SHIFT INTERLOCK SYSTEMS»(ref-144214) .
  7. Install column upper cover, light control switch and headlight dimmer switch, wiper and washer switch and spiral cable : Install the column upper cover.
